[Medico-surgical management of renal leiomyosarcoma]. / Manejo médico-quirúrgico del leiomiosarcoma renal.

Because renal leiomyosarcoma is extremely rare, the experience in the management of this tumor type is necessarily scant. Our surgical and chemotherapeutic approach in a 17-year-old male patient with renal leiomyosarcoma achieved partial remission of tumor recurrence and a survival of 31 months following diagnosis.

[2 new cases of ++urethral diverticuli in women]. / Dos nuevos casos de divertículos uretrales femeninos.

The first two cases of diverticulum of the female urethra seen in our Service are described. The secretion of purulent material from the urethra on vaginal compression prompted us to suspect this condition, which could not be confirmed radiologically in one case and a urethroscopy procedure was required. The etiopathogenesis of this disease is briefly reviewed and the therapeutic possibilities depending on the location of the urethral diverticulum are discussed.

[Lymphatic involvement predominating and revealing prostatic carcinoma]. / Afectación linfática predominante y reveladora en el carcinoma prostático.

The lymphatic system is the most common site of metastasis of prostatic carcinoma. However, carcinoma of the prostate presenting as lymphadenopathy is rare. It can present at any site and may sometimes mimic lymphoreticular tumors. The diagnosis is based on the histological findings. Histochemical techniques using immunoperoxidase demonstration of acid phosphatase and prostate specific antigen are fundamental in detecting the occult tumor of the prostate. Treatment is palliative and enlargement may occasionally remit with hormone therapy. The prognosis is invariably poor. Survival is less than 5 years irrespective of the response to treatment. Three cases are described herein: 2 presented as retroperitoneal mass and 1 as left lateral cervical lymphadenopathy.

[Spontaneous extravasation of urine secondary to bladder carcinoma. Non-invasive therapy]. / Extravasación espontánea de orina secundaria a carcinoma vesical. Terapéutica no invasiva.

A case of spontaneous urinary extravasation secondary to bladder carcinoma is described. The patient received systemic polychemotherapy which reduced tumor size and resolved renal ectasia and urinary extravasation. Spontaneous urinary extravasation secondary to bladder carcinoma is rare. For this reason we considered it of interest to report this case.

[Primary retroperitoneal hydatidosis]. / Hidatidosis retroperitoneal primaria.

The case of a primary retroperitoneal hydatidosis in a 62 year-old patient found accidentally during an haematuria study is presented. Both the possible extraperitonization mechanisms and efficacy of ultrasound scanning and percutaneous puncture in the etiological diagnosis in cases of retroperitoneal mass are evaluated.

[Bilateral renal adenocarcinoma: relationship with phakomatosis]. / Adenocarcinoma renal bilateral: relación con la facomatosis.

Von Hippel-Lindau disease is a very uncommon finding in our environment. A case of an incidental finding of that entity expressed through retinal angioma, bilateral renal cysts and bilateral renal carcinoma is described. A surgical course was followed performing a radical left nephrectomy, given the large size of the tumour, and right lower partial nephrectomy, as well as a review of the renal cysts considering the big tendency they have to degenerate in the disease.

[Kidney hydatidosis]. / Hidatidosis renal.

Seven cases of hydatid renal cyst seen at our department over the past 8 years are described. The literature is reviewed and the importance of conservative surgery in the treatment of this disease is highlighted.

[An infrequent form of metastasis of carcinoma of the prostate]. / Forma infrecuente de metástasis de un carcinoma prostático.

A case of carcinoma of the prostate metastatic to breast is reported. We highlight its rarity, its relationship with estrogen treatment, and the poor prognosis of this condition which develops in the end stages of metastatic carcinoma of prostate.

[Glans penis necrosis secondary to gentian violet treatment]. / Necrosis de glande secundaria al violeta de genciana.

We describe a patient who developed superficial necrosis of the glans penis from irritation after topical treatment with 1% gentian violet. The foregoing condition resolved after withdrawal of treatment. A differential diagnosis (sexually transmitted diseases, epidermoid carcinoma, etc.) is warranted on finding this type of lesion in the glans penis.

[Reno-colic fistula]. / Fístula renocólica.

Nephro-intestinal fistulas involve the GI tract and the kidney or pyelocalyceal system. The main causes may be urologic or digestive, the site diverse. Reno-colic fistulas, although rare, are more frequently observed. We describe a case of left reno-colic fistula secondary to lithiasic pyonephrosis that presented as sepsis. Diagnosis was confirmed by retrograde pyelography. Treatment was by surgery (left nephrectomy, closure of the fistula, and colonorhaphy).

[Association of 2 prostatic tumors]. / Asociación de dos tumores prostáticos.

We report on a case of primary transitional cell carcinoma of the prostate associated with focal prostatic carcinoma, incidentally discovered after TUR of the prostate. An underlying bladder tumor was discarded by randomized TUR of the bladder and serial cytologic analyses.

[Incidental adrenal tumor: non-functioning cortical adenoma]. / Incidentaloma suprarrenal: adenoma cortical no funcionante.

Adrenal incidental tumors are masses incidentally discovered on ultrasonography or CT for other abdominal disorders. Management depends on tumor size, nature, content, and hormonal behaviour. We report on a large, nonfunctioning adrenocortical adenoma that was incidentally discovered in a 59-year-old male patient with right-sided costo-lumbar trauma.
